microBOX 25A is medium power reducer, designed to work in lighting network,

in which it is possible to reduce power consumption by reducing voltage. Due to its small size and low weight it will fit in almost any lighting cabinet. The device uses the transformer method of lowering voltage and power at the same time, which allows energy savings of up to 40%. With this solution we extend the life of luminaires, ballasts and light sources, as well as lower the additional costs of operation and maintenance of the lighting networks. microBOX does not introduce harmonic distortion and does not adversely affect the work of lighting.
The device is equipped with thermal protection: internal temperature sensor that if required switches the device off and indicates exceeding the allowed temperature. On the front panel of the device there is a switch that allows the user to easily select the appropriate voltage or, if necessary, a manual bypass.
